Overview

The RennTech R3 Performance Package for the 2017-2023 C 63 / C 63 S AMG Coupe combines parts that RennTech developed and tested together, so you get a matched setup rather than a pile of separate upgrades. RennTech rates the car at 767 hp and 633 lb-ft with this upgrade.

Key details

R3 brings the ECU upgrade, sport mufflers, BOV adapter, high-flow filter, fuel system upgrade and Stage II turbos for gains of up to 222 hp and 83 lb-ft. The forged billet turbo wheels pair a larger compressor inducer with a bigger turbine trim.
